12-GHz Photoreceivers Appendix I: Microwave Connectors • 15
Appendix I: Microwave Connectors
The performance you obtain from the Model 1580-A
photoreceiver depends largely on the instruments you
use to measure their outputs and how the connections
are made to the instruments.
Connect the male connector of the photoreceiver
directly to the female connector of the instrument.
(For the low-frequency version, be sure to include a DC
block between the receiver and the instrument.)
If you need to use an adapter, make sure it is designed
for your frequency range of interest. The following
table lists a few connectors and the frequency ranges in
which they may be used. For more information,
request Application Note 1. If you use an intervening
coaxial cable, select a cable with sufficiently low loss in
the frequency range of interest.
